Be it knovvn tht 1, JoIN 11ABTIN KRoNB, o oitizen of tho tTnitod Stafes, reSiding af Au- Toro, in the ooonty of 1no and State of I11inoiS, havo invenfed oertain neW and uSeful ImproveInentS in 1V1ef1 fIubS, of Whioh tho fo1- lowing iS a Speoifioation, roforonoo boi had to tho aooompanying drWingS, Whioh aro made part heroof, and io Whioh Eigofo 1 iS a viow of tho ontire hnb ShoWn pary in vortioal Seotion. EigS. 2, 3, 5 and 6 aro dotaned vioWS of tho elotnontS Whofe from tho Inetal hnb iS oompoSed or bl1ilt up,

Sin1ilaI' lotters rofer to SinlilarparfS throughont tho Sevorl vieWS.

The objeot of the preSent invention iS fo provide 111ofal hub of suoh a oonStruofion, tht the aSSembHng of a sorieS of portS fnrniShed With Straight oylindrioal oXterioI' and oorroSponding interioI' S11rfaJooS, vvithout any SofowthroadS or fapping, if So deSired, Will fo- Solt in a ooolpleto hub, the voriouS partS Whoreof may thon bo figidly onifodogether by brazing, Soldering or anyequivolent IneanS.

Fho mofal hob oonSiStS of the following paftS: the ooter tube 0, Eigs. 1 and 3, the in nef tube f, 1 igS. 1 alnd 3 tho fWo an eS and igS. 1, 4, and o, two buShingS o, Eigs. 1 and 6 and, prefofaJbly, bot not neoeSSarily aS wiH be shown hereinafter, of a soreW S, Ei 1.

The Defal hub, ig. 1, iS pnt together from ifs oonStituent ports i1 tho follov7ing Inanner: Upon eaoh of the extrome ends of the onter tI1be 0, Eig. 3, ore foroed tWo Similar flanges ig. 1, With their oylindrioal oponingS 0 ig. 5. I prefeI to SoldoI of brazo ngeS and fo the onter tubo 0, not Wishing to employ any othor IneanS of uniting theSe partS together, as by pinning of Sorewing. 1he nangeS are furniShed with aJ noInber of holeS S 9, Fi vvherein the n]etal S okes, cuStomar in SimHar oonstrnofionS, re Seoured. Tho two onnnlar ieoeS o, Ei S. 1 and 6, known in the arf aS buShinS and deStined to furniSh a hard and Snooth oll1ng Sorfaoo to tho beaf in baHS Which are ordinaril em lo ed in oonneofion with Sooh o1etal hubo are to be inserted into tho endS of tubo 0 in snoh a lTJanner aS to Seoore thenJ againSf laforal diS- plaoomont byany Stfoin Whioh may bo broughf opon tho11 Whon tho hub is in aotoal Serviool ThiS iS aooon1p1iShed by plaoing into tho iI1- terior of tobe 0 another tube f, oaJllod the iI1- ner tube, and Snug]y tting the intorior of tube Said inner tobef being of suoh a length as to beor agoinSt tho f1t Sn rfaoo of both boSh ingS o when tho edge of their oonoave Side iS fluSh With tho outer edgoS of angeS and adod with the oxtreTne endS of tobe 0. To Se oure the inner tobe f against diSplooeInent, I refer to em lo a Sorew S 1i 1, Which aSSeS throogh an apoffore S of onter tubo 0, Eig. 3, af1(1 into a similar one So 1 ig. 2 of inner tnb the aperturo in the 1atteI' boing tpped vvith a thread oorrespondiog vvith Srno on sorew S I ig. 1. TobeS 0 and f oould alSo be onite(1 by brazing or Soldering or dffving a pin into apertores S1, 1 igs. 2 and 3, but for il1uSfrativoprposeS in nly drWingS, I pfe fof to ShoWthe method of uniting tobeS 0 and f by a solaJll soreW S, ig. 1, not oonnfng 111y Self to this 1etho(1 howover.

By the obovo noent1one(1 oonStrnotion, I obtain a Seouro and ooorte soot and fastening for buShingS o Withoof boring, reaming of oofting a reoeSS into ondS of tnbo 0 to forIn aJ Shouldo1' fof the edge of flot soffaoo of boSh ingS o fo abot againSt of withont forming au oifoolaMr aDge roond faoo of bnshiogs o to I'eSt npon extrerne en(1S of tubo 0 or of ngeS and both of whioh perfonnanooS I desire to avoid, boing ooStly and ofton inaoonrato.

I aII1 aWare that riort0 In invention,ball bearing Inotal h111)S hove been Iade from oy lindrio1 tubeS, With soparato f1angeS and bushings fted thoreto I therefore do I1ot olaim sooh a oo1111)inotion broodly, bof

vhot I do olain1 aS Iny invention, and doSiro to Seoore by IotterS I tent, iS

1. In a Ineto1 hub, the ooolbinofion of on innef and an onterpieoo of oy1indriol tubing, a pair of HongeS With plain oyHndrio1 aper toroS and a pair of bushingS of aJ plin oyHn driCa1 exterior, SubSfntiaHy os Set fofth.

2. In nJeta1 hob, the oombination of an inner and an ooterpieoe of oylindrioa1 tnbing, a pir of ngeS With plain oyHndrioa1 pef tureS and a pair of buShings of a pla.in oyHodfio1 exterior, the flangeS boing Seoufed fo the ootor tobing by nleons of bfazing or 501- dofing, SobStanfially as desoribed.

3. In a IIletol hub, tho ooo1binatioo of on inner and an outef pieoe of oy1indfioo1 tnbing,

pir of flangeS Wifh plain oy'li11drioal aper- Ioo tureS and a pair of buShings of a plain oy1in dfioa1 eXterior, and 111enS for Tigidly seouring tho outor and inne oy1indrio1 tubeS to oaoh other, for the pufposo and in tho Inanner, SnbStantiaHy aS Sot forth.

The oornbintion, in a lIletaJl hub, of an inner and n outer piooe of oy1in(1rio1 tubing, a pair of ngoS With plain oy1indrio1 pertnreS and apair of bnShingS of a plain oy1in drioa1 oxtorior, Said buShingS abutting ginSt tho endS of tho inner tnbe, SubStntiHy aS Sof forth.

5. The oombination in Inotal hub, of on innof and an outor piooo of oylindrioa1 tubing, pir of ngeS With plain oylindrioal apeffureS and a pir of bnshings of aJ plain oylindrioal eXterior, the innef tubo With ftS extorior oloSely fLtting tbe intefior of outer tnbo and the endS of inner tubo forn1ing ShonlderS of SeatS for the bushingS to but aginst, Snb StaI1tially S Set forth.
